A buffer solution was prepared by combining 50.0 mL of 6.0 M acetic acid sõlution and 25 g of sodium acetate (NaCH3C00) with enough water to make 1.0 L of solution. What
is the pH of this buffer solution? The value of K, for acetic acid is 1.8 x 10-

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
